Provided is a wind detection apparatus which can accurately detect wind. The wind detection apparatus 1 comprises a plurality of microphones 11, 12, a spectrum analyzer unit 22 for acquiring a frequency characteristic representing a sound pressure at each frequency band area from a plurality of sound signals detected by the two microphones 11, 12, a sound pressure/dispersion comparison unit 23 for comparing the acquired frequency characteristics (sound pressure/dispersion) of the two microphones 11, 12, and a wind determination unit 24. The wind determination unit 24 determines in accordance with the comparison results of the sound pressure/dispersion comparison unit 23 that the sounds detected by the two microphones 11, 12 are wind sounds when the difference between the sound pressures of the two microphones 11, 12 is detected throughout the predetermined frequency band areas. |
